ZELENIT FERTILISER Russian patent published in 2010 - IPC C05D9/02 C05G3/00 A01N37/44 A01N59/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to agriculture and specifically to plant fertiliser containing basic fertiliser elements (macroelements), nitrogen, phosphorus and potassium, as well as microelements which are necessary for normal growth and development of plants. The fertiliser, which is based on a polymer matrix containing carboxylic acid fragments, contains 30-93 wt % fragments of unsaturated carboxylic acids selected from the following group of monomers: glutamic, methacrylic, acrylic, alginic, maleic, fumaric and lactic acid, 1.0-32.5 wt % N-vinylamide, and also contains 0.7-62.7 wt % salts containing macroelements selected from a group comprising nitrogen, phosphorus and potassium, and 0.01-0.1 wt % microelements - iron, copper, molybdenum, zinc, boron, manganese, cobalt and magnesium salts or sulphur.

EFFECT: use of polymer fertiliser Zelenit as top-dressing fertiliser enables creation of a rational system of mineral nutrition, sharply increases resistance of the productive phytocoenosis to unfavourable weather conditions, cuts the amount of mineral fertiliser used, improves the quality and yield and significantly increases profitability of agricultural production.
